Did you know?
Fans of fine French wine and cuisine won't be surprised to hear that the French language gave us a number of words for those who enjoy good living and good eating. "Gourmet," "gourmand," and "gastronome" come from French, as does "bon vivant." In the late 17th century, English speakers borrowed this French phrase, which literally means "good liver." No, we don't mean "liver," as in that iron-rich food your mother made you eat. We mean "liver," as in "one who lives" — in this case, "one who lives well."
